The main drafters of this standard. Chen Yunxia, Yang Weiguo, Gao Zhijiang, Wang Jun, Jiao Liwei, Zhao Ming, Cheng Yuanxin, Xiao Shouliang, Li Healthy. Cottonseed husk

1 Scope

This standard specifies the terms and definitions, quality requirements, inspection methods, inspection rules and identification, packaging, transportation and storage of cottonseed husks. Claim. This standard applies to the processing, trade, storage, transportation and use of cottonseed hull products.

2 Normative references

The following documents are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all amendments) applies to this document.

3 terms and definitions

The following terms and definitions apply to this document. 3.1 Shell that has been broken and separated from cottonseed kernels. [GB/T 32139-2015, definition 2.4.30] 3.2 Moisture moisture The weight of moisture in the cottonseed hull as a percentage of the total weight. 3.3 Foreign matters Other than cottonseed husks and cottonseed kernels. Note. such as gravel, bricks, earth, etc. 3.4 pH pondus hydrogeni A certain amount of water is added to the cottonseed husk, and the resulting solution exhibits a pH.

4 Quality requirements

4.1 sensory traits See Table 1 for sensory trait requirements. Table 1 Requirements for sensory traits of cottonseed husks Project requirements Appearance is white or off-white, no agglomeration, no mildew, no insects, no obvious flocks, and no obvious cotton seed kernels. Odor Cottonseed husk has unique odor and no irritating odor. No visible impurities such as obvious sediment. 4.2 Quality classification index It is divided into three levels according to the three quality indicators of moisture, impurities, and pH, as shown in Table 2. Table 2 Quality classification of cottonseed hull products Level 1 Level 2 Level 3 Moisture /% ≤14.0 14.0 ＜ X≤16.0 ＞ 16.0 Impurities /% ≤1.0 1.0 ＜ X≤2.0 ＞ 2.0 pH value 6.0 ～ 7.3 ＜ 6.0 or ＞ 7.3

5 Inspection method

5.1 Sampling Implemented in accordance with the provisions of GB 5491. 5.2 Sensory traits Visually inspect the appearance and impurities, and smell the nose. 5.3 Determination of moisture According to the direct drying method in GB 5009.3. 5.4 Determination of impurities 5.4.1 Principle The impurities are separated from the cottonseed hull by screening, and the percentage of the weight of the screened impurities in the sample weight is the impurity content. 5.4.2 Instrument 5.4.2.1 Balance, Sensitivity 0.01 g; 5.4.2.2 18 mesh standard sieve. 5.4.3 Operation steps Reduce the sample to be tested to about 500 g (accurate to 0.01 g) by the quarter method, weigh the sample M0; place the sample on a clean paper. First sifter through an 18-mesh standard sieve, take the sieve, count it as impurities, and weigh the impurity M1 (accurate to 0.01 g). Seed kernels are not counted as impurities. 5.4.4 Calculation results The impurity content is calculated according to formula (1). 1  (1) In the formula. A--The content of impurities in the sample,% M1--Weight of impurities in sample, g M0--sample weight, g Results Take the arithmetic mean of two independent determinations obtained under repeatability conditions, with one decimal place. 5.4.5 Precision The absolute value of the difference between two independent determination results obtained under repeated conditions is not greater than 0.2%. 5.5 Determination of pH 5.5.1 Preparation of sample solution Weigh a (50 ± 5) g sample with a balance with an accuracy of 0.01 g, place it in a 500 mL conical flask, add 250 mL of water, After sealing, fix it vertically on the shaker, adjust the oscillation frequency to (120 ± 10) times/min, shake for 30 minutes, and then stand for 30 minutes Then, the sample was filtered with a neutral filter paper, and the pH value of the filtrate was measured immediately after the filtration. 5.5.2 Analysis method Determined according to the method in NY/T 1377. It is expressed as the arithmetic mean of two independent determination results obtained under repeatable conditions, and the result is rounded to one decimal place. 5.5.3 Precision The absolute value of the difference between the two measurements obtained under repeatable conditions is not greater than 0.5.

6 Inspection rules
